Using HBase

Available in VPC

Apache HBase is a HDFS-based data storage where it's possible to randomly read and write in real time. You should understand the application's data access patterns and check beforehand if HBase can be used efficiently.

Check HBase app details

When the app creation is completed, you can view the details. When the Status is Stable under the app's details, it means the app is running normally.
The following describes how to check the app details.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Data Forest > App menus, in that order.
2. Select the account that owns the app.
3. Click the app whose details you want to view.
4. View the app details.
   

• Quick links
  • AppMaster: URL where the container log can be viewed When creating apps, all apps are submitted to the YARN queue. YARN provides a web UI where each app's details can be viewed.
  • HBase RegionServer-0 Status UI: URL for managing HBase region server status
  • HBase Master Status UI: HBase's Master UI
  • Component: The HBASE-2.0.0 or HBASE-2.2.3 app types consist of the master, region server, thrift, thrift2, and rest components.
    • hbasemaster: You can manage region servers and monitor them by using Zookeeper.
    • regionserver: You can manage regions and process client requests.
    • thrift: API server required to exchange data with HBase
    • thrift2: API server with the concurrent feature added to thrift
    • rest: API server that uses the rest method

Cautions for using HBase

When you have to destroy the HBase app, delete the Zookeeper path used by the app, zookeeper.znode.paren. Problems may occur if you recreate the HBase app with an identical name without deleting the Zookeeper app path.
